Lisa Roupas

Secretary

With 17 years of experience as a nurse practitioner, I have built a career spanning hospital medicine, general surgery and bariatric care. Beginning with 4 years as a hospitalist and 13 years in general surgery, I now specialize in bariatric surgery and weight management, helping patients achieve long-term health and wellness.


Prior to becoming a nurse practitioner, I worked as a registered nurse in oncology and the medical ICU, experiences that shaped a deep commitment to compassionate, patient-centered care. Beyond clinical practice, I have served on the board of the York County Medical Foundation for the past decade, helping with local and global health initiatives.  My dedication to global service is also seen in my board role with Living Word Church's Global Missions and with the Isaac Ishmael Initiative through Accord, as well as ongoing volunteer work on international medical and surgical trips since 2020.  I am passionate about connecting with people from all backgrounds, striving to ensure every patient and community member feels seen, valued and known.
